최근에 초전자 제품 및 고주파를 사용하는 전기전자 장비가 소형·경량화 되고 일상생활에서 흔히 사용되고 있는 컴퓨터, 핸드폰, 모니터, 프린터 및 동영상 카메라와 같은 가전제품들은 더 빨리 소형화, 고성능화 되는 추세이다. 가전제품들이 소형·경량화될 수록 전기사용에 따른 발열량은 급격히 증가하게 되기 때문에 열이 집중되지 않도록 방열시켜 주어야 하는 문제점이 발생된다. 이들 전자제품의 소형화에 따라 내부배선에 사용되고 있는 절연전선 또한 얇아지고, 단위면적당 발생되는 발열량이 증가하기 때문에 높은 내열성 및 절연성을 요구하게 되었으며, 전류가 흐를 때 발생하는 열의 방출을 신속하게 해주는 기능이 필요하게 되었다. Recently, electric and electronic equipment using high-frequency electronics and high frequency are becoming smaller and lighter, and home appliances such as computers, mobile phones, monitors, printers, and video cameras, which are commonly used in daily life, are becoming smaller and faster. As home appliances become smaller and lighter, the amount of heat generated by the use of electricity increases sharply, causing heat dissipation so that heat is not concentrated. As these electronic products become smaller, insulated wires used for internal wiring also become thinner, and heat generation generated per unit area increases, requiring high heat resistance and insulation properties, and a function for quickly dissipating heat generated when current flows. It became necessary.
종래의 다층 절연전선의 절연피복재로 사용되는 폴리에스텔, 폴리아미드, 폴리에테르 설폰 및 폴리에테르이미드 같은 고분자수지는 내열성, 전기절연성은 물론 기계적강도가 우수하지만 열전전도가 낮아 도체에서 발생하는 열을 쉽게 배출할 수 없다는 단점을 가지고 있어 과전압 시 발생하는 고열에 의한 화재발생 위험을 안고 있는 실정이었다.Polymer resins such as polyester, polyamide, polyether sulfone, and polyetherimide, which are used as insulating coating materials of conventional multilayer insulated wires, have excellent heat resistance, electrical insulation and mechanical strength, but have low thermal conductivity to easily conduct heat generated from conductors. Due to the disadvantage that it can not be discharged was a situation that there is a risk of fire caused by high heat generated during overvoltage.
본 발명은 상기와 같은 문제점을 고려하여 이루어진 것으로, 그 목적은 절연전선에서 발생하는 고온의 열을 쉽게 방출시켜 휴대용 전자제품에 친근감을 부여할 뿐만 아니라, 상용전압 혹은 산업용 전자제품에 있어 발생하는 고열을 쉽게 방출시킴으로서 화재발생을 예방할 수 있는 방열 다층절연전선을 제공함에 있다.The present invention has been made in view of the above problems, and the object thereof is to easily release high temperature heat generated from an insulated wire, thereby providing a feeling of familiarity to portable electronic products, as well as high temperature generated in commercial voltage or industrial electronic products. It is to provide a heat dissipation multilayer insulated wire that can prevent fire by releasing easily.

표 2은 방열충진제로 사용되는 수지의 열전도도를 나타내고 있다.Table 2 shows the thermal conductivity of the resin used as a heat radiation filler.
하기 표 3, 4, 5에서 제조된 방열 다층전열전선의 성능은 절연파괴전압, 납땜성, 열전도도 및 난연성실험에 의해 평가된다.The performance of the heat dissipated multilayer electric wires prepared in Tables 3, 4, and 5 is evaluated by dielectric breakdown voltage, solderability, thermal conductivity, and flame retardancy test.
상기 표에 기재된 압출피복 시, 실린더 온도는 160 내지 360℃, 스크류 회전수는 20 내지 30 rpm 그리고 선속은 100 내지 500 rpm으로 제어하여 편심이 발생하지 않도록 압출 절연하였다. In the extrusion coating described in the above table, the cylinder temperature was 160 to 360 ° C., the screw rotation speed was controlled to 20 to 30 rpm, and the line speed was 100 to 500 rpm to extrude insulation to prevent eccentricity.
난연성 실험은 난연 시험기를 이용하여 수평시험법(UL 94HB)의 시험 방법에 따라 측정하였으며 그 난연성에 따라 V-0, V-1, V-2로 구분하며, V-2이하이면 불합격 판정한다.The flame retardant test was measured according to the test method of the Horizontal Test Method (UL 94HB) using a flame retardant tester, and classified into V-0, V-1, and V-2 according to the flame retardancy.
납땜성은 KS C 3006의 16항과 같이 동일한 보빈으로부터 길이 약 15㎝의 시험편 34개를 취하고 각각에 대하여 규정된 온도로 유지된 KSD 6704에 규정한 50Sn 중에 시험편의 앞 끝부분 약 40mm를 규정된 시간동안 담근 후 꺼내어 즉시 적당한 헝겊으로 가볍게 닦아냈을 때 담긴 부분의 윗부분 약 10mm를 제외하고 납땜이 고르게 되었는지로 판단하였다. Solderability is defined by taking 34 specimens of approximately 15 cm in length from the same bobbin as specified in clause 16 of KS C 3006 and maintaining the specified temperature for each of approximately 40 mm at the front end of the specimen in 50 Sn specified in KSD 6704. It was judged whether the solder was evenly removed except for about 10 mm of the upper part of the contained part when soaked and then removed and immediately wiped with a suitable cloth.
절연파괴전압은 두 줄 꼬임법으로 측정하였으며, 동일한 보빈으로부터 길이 약 50㎝의 시험편 3개를 취하고 각각을 두개로 접어서 합친 다음, 적당한 인장력을 가하면서 약 12㎝ 길이의 부분을 적당한 꼬임수로 꼰 후 인장력을 제거하고서 접은 부분을 자르고 60㎐의 정현파에 가까운 교류전압을 가하여 측정하였으며, 절연파괴전압이 변압기에 사용되는 가장 높은 실험치인 14kV 보다 낮으면 불합격 판정한다. The breakdown voltage was measured by two-wire twisting method. Take three specimens of about 50cm in length from the same bobbin, fold them together in two pieces, and twist the parts of about 12cm in length with appropriate twisting force while applying the appropriate tension. After removing the tensile force, the folded part was cut and measured by applying an alternating voltage close to the sine wave of 60㎐. If the insulation breakdown voltage was lower than 14kV, the highest experimental value used in the transformer, it failed.

It is formed of an extruded insulated outer coating layer made of heat-resistant high-molecular resin, and has excellent heat resistance, abrasion resistance, and electrical insulation, and easily releases high-temperature heat generated from an insulated wire, thereby providing familiarity to portable electronic products. Easily dissipates high heat generated in electronic products to prevent fire, and has the advantage that can be applied to products that require heat dissipation such as transformers, home appliances, airplanes, cordless phones, computers.
